Torsionometer

Offers the advantage of being compact and portable, quick to perform and easy for both patient and examiner. The patients view of the test has minimal cues about objective parallelism. The patient moves the green line until it is parallel with the red line. On the back of the test plate is a measurement scale corresponding to the orientation of the green line relative to the red line. This enables the examiner alone to read the amount of torsion present.
